We have this issue too...mostly I just pull the blanket up and straighten it a bit and fluff the pillow a bit...DS doesn't have a top sheet, and has fitted one on the mattress. So I don't actually 'make' the bed, I just neaten it a bit lol. When the sheets need to be changed I get DH to pull the mattress down onto the floor, then I change the sheets and quilt cover/pillowcase and it all gets put back up top.
